Book Description
John Waller describes the changing ideas concerning heredity from antiquity to the modern biological understanding, considering both the efforts over the centuries to identify the physiological mechanisms involved and how views of heredity have been used to justify or condemn inequalities of class, gender, and race.

Book Description
Excerpt from The Heredity of Acquired Characters in Plants The object of this book is to prove that Evolution - so far as Plants are concerned - depends upon the Inheritance of Acquired Characters. This was Darwin's contention. Dr Weismann and his followers assert that no such characters can ever be hereditary unless the influence of the environment can reach and affect the reproductive organs, or his hypothetical substance "germ-plasm." As all the characters of the vegetative system, or the soma of plants, which are regarded as specific, are acquired long before any reproductive organs exist at all, and therefore before any vegetative cell has begun to assume a reproductive character, Dr Weismann's proviso is inappplicable to plants.

Book Description
A riveting explanation of epigenetics, offering startling insights into our inheritable traits. In the 1700s, Jean-Baptiste Lamarck first described epigenetics to explain the inheritance of acquired characteristics; however, his theory was supplanted in the 1800s by Darwin's theory of evolution by natural selection through heritable genetic mutations. But natural selection could not adequately explain how rapidly species re-diversified and repopulated after mass extinctions. Now advances in the study of DNA and RNA have resurrected epigenetics, which can create radical physical and physiological changes in subsequent generations by the simple addition of a single small molecule, thus passing along a propensity for molecules to attach in the same places in the next generation. Epigenetics is a complex process, but paleontologist and astrobiologist Peter Ward breaks it down for general readers, using the epigenetic paradigm to reexamine how the history of our species-from deep time to the outbreak of the Black Plague and into the present-has left its mark on our physiology, behavior, and intelligence. Most alarming are chapters about epigenetic changes we are undergoing now triggered by toxins, environmental pollutants, famine, poor nutrition, and overexposure to violence. Lamarck's Revenge is an eye-opening and provocative exploration of how traits are inherited, and how outside influences drive what we pass along to our progeny.
